SUSPENSION-FIXTURE.

SPEGIFECATION forming part of Letters Patent N o. 735,613, dated August 4, 1903. Application filed February 2, 1903. Serial No. 141,565. (No model.)

T0 all whom, it weary concern:

Be it known that I, Louis STEINBERGER, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the vcounty of Kings and State of New York, have invented a new and Improved Suspension-Fixture, of which the following is a full, clear, and exact description.

My invention relates to a suspension-fixture to be used in overhead-line construction for electric railways, and more particularly asadevice capable of servingasaturnbuckle, a strain, and a clip-support.

Heretofore in supporting trolley-wires an electric cables it has been customary to employ separate devices to accomplish the three purposes mentioned--that is to say, turnbuckles are used for lengthening and shortening the wires, strains are employed to effeet electrical disconnection of one wire from another where the wires are mechanically connected, and a hanger or similar support is placed upon the span-wires for the purpose of supporting the clip. p

To produce a device capable of serving in one or more of the capacities mentioned is the object of the present invention.

I do not limit myself to the particular structure herein shown, nor to a spherical form of the metallic frame portion, nor to the 1 spherical outer insulated portion, nor to three extensions. Any other number may be used for certain purposes without departing from the spirit of my invention. This style of iixture may also be used with very good effect on curves and around corners.

Referenceis to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a central vertical section thron gh' my combination suspension-fixture. Fig. 2 is a somewhat similar view showing in elevation certain .portions of the clip-support and also showing the clip. Fig. 3 is a central vertical section upon theline 3 3 of Fig. 1 looking toward the left, and Fig. 4 is a front elevation of the annular metallic member 1 re moved from the device.

A hollow member 1, of a general annular form and preferably having the particular conformity of a sphere mutilated by a central cylindrical passage'2 and by substantially fiat faces 3, 4, and 5, is removably tted with sleeves 6 7 8 of insulation, provided integrally with {ianges 6a 7* 8a of the same material. The sleeves and anges together constitute washers, vas indicated in Figs. l and 2. Metallic sleeves 9 10 are provided with integral shoulders l1 12 and with threads 13 14 of opposite pitch, these threads being engaged by screw-bolts 15 16, provided, respectively, with left and right hand threads and with suspension-eyes 17 18. The washers 19 20, of insulating material,are made of annular form and are fitted against the shoulders 11 12. Revoluble nuts 21 22 are tted upon the inner ends of the sleeves 9 10, which are threaded for the purpose, as indicated more particularly in Figs. 1 and 2. The inner ends of these sleeves are further provided with slots 23 24, which engage the insulation, thereby preventing the sleeves from turning. A post 25 is provided with a threaded portion 26,upon which the clip 27 may bescrewed. This post 25 is tted against a washer 28 and is provided with a cylindrical portion 30a and with a slot 30, the cylindrical portion 30"l being partially threaded and also being engaged by the nut 29, the slot 30 engaging the insulation 31, as aboveY described with reference to the slots 23 24.

The annular portion 1 may be drop-forged or cast' or may be formed by boring outa solid sphere of metal. The sleeves or washers 6 6i 7 7a 8 8 are disposed radially, the same as the apertures in which they engage. The sleeves 9 10 are preferably in alinement with each other, as is usually the case with turnbuckle members.

The device isassembled as follows: The annular portion 1 being provided with its several apertures, as above described,r the sleeves 9 10 and the post 25 are fitted with the washers 19, 20, and 28 and are inserted into position, the washers 6 6a 7 7a S 3a being inserted from theinterior of the annular portion and the revoluble nuts 2l, 22, and 29 being screwed firmly into position. By this means a complete turnbuckle is formed, the screw members 15 16 being free to rotate and to virtually lengthen and shorten the wire or IOO cable. The post 25, provided with its threaded portion 2b', may be used as a handle for turning the spherical portion of the turnbuckle, as indicated in Fig. 1. The insulation is now applied in any approved manner, being preferably set by pressure.

When the device is used as a strain, the suspension-eyes 17 18 are turned in the screwbolts 16 and are forced firmly against the bottoms of the sleeves 9 10, as indicated in Fig. 2. The screws being thusvtightened, no relative movement of any part is permitted, and the device of course acts as a strain.

The device may be used as a clip-support whether the sleeves 9 10 and their accompanying parts are used as a strain or as a turnbuckle. A very good way to use the device is to first tighten the hanger wires, as if using a turnbuckle, then force the screwbolts 15 16 firmly into the position indicated in Fig. 2, whereby they become stationary, meanwhile using the post 25 as a handle for the purpose of rotating the spherical portion, and finally after securing the screw-bolts 15 16 firmly against the bottoms of the sleeves 9 10 the clip 27 is mounted upon the threaded portion 26. f
